What does summarize do?
summarize is a skill that teaches Claude to use the summarize.sh command-line tool on URLs, local files such as PDFs, and YouTube links. Claude runs summarize with the link or path and returns the result. For videos it can add --youtube auto --extract to pull a rough transcript, and when a transcript is huge it gives a short summary first and asks which part to expand. Flags set the length, cap output tokens, print raw extracted text or return JSON. The tool needs an API key for OpenAI, Anthropic, xAI or Google, and can use Firecrawl for blocked sites and Apify as a YouTube fallback.
When should you use summarize?
Use it when
- You want the gist of a long article or video
- You need a YouTube transcript without yt-dlp
- You want a PDF condensed to a set length
Skip it when
- You can't install the summarize CLI with Homebrew
- You don't want content sent to an outside model provider
What it needs and what it can touch
You need
- The summarize CLI (Homebrew formula steipete/tap/summarize)

- Firecrawl or Apify keys (optional)
What it can do
- Runs shell commands (summarize)
- Reads local files you point it at
